Document Type and Number:
WIPO Patent Application WO/2023/213130
Kind Code:
A1
Abstract:
Provided are a laser range finder in which optical transmission and receiving are coaxial, and an optical module. By optimally designing the structures and positions of parts such as a lens barrel, an objective lens (3), an eyepiece (4), an optical module, a laser emitter (1) and a laser receiver (2), the laser emitter (1) and the laser receiver (2) are disposed on a side surface of a main light path, but the objective lens (3), the eyepiece (4) and two light splitting prisms (51, 52) in the optical module are disposed on the main light path. The light splitting prisms (51, 52) are used for changing the paths of a transmitting light path and a receiving light path, such that the transmitting light path and the receiving light path are coaxial in the main optical path, and thus a target can be aligned and the distance can be measured more accurately, and a user can directly and visually observe said target.
